Inn Stations is a great, very clean hostel in a decent part of Bangkok. The location isn't bad, where it's about a 20 minute walk from Chinatown and about fifty minutes by foot to the main attractions if you choose to walk. The hostel is also located right next to Bangkok's main railroad station as well as an MRT station which can make travel rather convenient.
The cleanliness of the hostel was superb, being one of the cleanest hostels I've stayed in. They also change your towels every few days as well.
If you are interested in exploring the city and even planning day trips out to the surrounding areas by train, I would highly recommend this hostel as it is a great place to sleep while conveniently nearby the other transportation options. Host communication was also excellent, making sure we had arrived and being ready for us to check-in, even at 2 AM in the morning.
